A Hurricane Warning means that hurricane conditions are expected
somewhere within the warning area. Preparations to protect life and
property should be rushed to completion.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area within 36 hours.

A Hurricane Watch means that hurricane conditions are possible
within the watch area. A watch is typically issued 48 hours
before the anticipated first occurrence of tropical-storm-force
winds, conditions that make outside preparations difficult or
dangerous.

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.

Interests elsewhere in the Lesser Antilles, Puerto Rico, and the
Dominican Republic should monitor the progress of this system.
Additional Hurricane and Tropical storm Warnings may be issued for
portion of the Leeward and Virgin Islands on Monday, and
Hurricane Watches will likely be issued for Puerto Rico and the
nearby islands Monday morning.

For storm information specific to your area in the United
States, including possible inland watches and warnings, please

DISCUSSION AND 48-HOUR OUTLOOK
——————————
At 1100 PM AST (0300 UTC), the center of Hurricane Maria was located
near latitude 14.2 North, longitude 58.4 West. Maria is moving
toward the west-northwest near 13 mph (20 km/h), and this motion
with a decrease in forward speed is expected through Tuesday night.
On the forecast track, the center of Maria will move across the
Leeward Islands late Monday and Monday night and then over the
extreme northeastern Caribbean Sea Tuesday and Tuesday night.

Maximum sustained winds have increased to near 85 mph (140 km/h)
with higher gusts. Rapid strengthening is forecast during the next
48 hours, and Maria is expected to become a major hurricane as it
moves through the Leeward Islands.

Hurricane-force winds extend outward up to 15 miles (30 km) from the
center and tropical-storm-force winds extend outward up to 105 miles
(165 km).

The estimated minimum central pressure is 979 mb (28.91 inches).

HAZARDS AFFECTING LAND
———————-
WIND: Hurricane conditions are first expected within portions of
the Leeward Islands by late Monday, with tropical storm conditions
beginning during the day on Monday. Hurricane conditions are
possible within the hurricane watch area by Tuesday, with tropical
storm conditions possible Monday night. Tropical storm conditions
are possible in the tropical storm watch area later tonight through
Monday night.

STORM SURGE: A dangerous storm surge accompanied by large and
destructive waves will raise water levels by as much as 5 to 7 feet
above normal tide levels near where the center of Maria moves
across the Leeward Islands.

RAINFALL: Maria is expected to produce total rain accumulations of
6 to 12 inches with isolated maximum amounts of 20 inches across the
central and southern Leeward Islands, including Puerto Rico and the
U.S. and British Virgin Islands, through Wednesday night. Maria is
also expected to produce total rain accumulations of 2 to 4 inches
with isolated maximum amounts of 8 inches over the remaining
northern Leeward Islands from Barbuda to Anguilla, as well as the
Windward Islands and Barbados. Rainfall on all of these islands
could cause life-threatening flash floods and mudslides.

SURF: Swells generated by Maria are affecting the Lesser Antilles.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local
weather office.
